CORN -HUSKER.

Application filed August 14, 1916, Serial No. 114,810. Renewed May To alt wiwmit may concewt:

Be it known that I, EARL BECKER, a c1t1- zen of the United States, residing at Ansonia, in the county of l\ ew Maven and State of Connecticut, have invented certain new and useful Improvements in Corn-Huskers, of which the following is a specification.

This invention relates to an improvement in corn huskers, and more particularly to devices of this nature such as are intended to be used in taking the ears from the stalks as they stand in the field and after husklng the same, to deposit the ears again upon the field between the rows of standing stalks where the ears may be readily gathered,

An object of my invention is to provide a machine which will straighten up the standing stalks and will take the ears therefrom by snapping or breaking the same off without injuring the ears or felling the stalks, and which will in this operation of breaking the ears from the stalks consequently remove a portion of the husk.

A. further object lies in PIOVlCllIlgdIlGtlIlS for directing ears of corn from the snapping rollers to the huskmg rollers.

With the above and other objects in vlew, my invention consists in certain novel constructions and combinations of parts which will be hereinafter set forth in connection with the drawings and then more particularly pointed out in claims.

In the drawings Figure 1 chine, v

Fig. 6 is a sectional view taken on the line 66 of Fig. 5, and V Fig. 7 is an enlarged detail sect1onal view of the lower end of the rollers wh1ch come in contact with the standing stalks.

The frame structure of the machine as generally designated at 1 is carried on the supporting wheel 2 at one side and has the power or bull wheel 3 mounted at the opposite side to form a part of the support and carrying means upon which the ma- Specification of Letters Patent.

chine may be moved over a field. A tongue 4 is connected with the main frame and has the double-tree 5 mounted thereon to permit thehitching of a team of draft-animals, although it will of course be understood that Patented Oct. 12, 1920. e

a motor or other mechanical power means might be arranged to propel the machine. A frame 6 is mounted on the main frame to one side thereof to extend upwardly and disposed angularly toward the rear, and a supporting 6, the last mentioned frame being dropped somewhat at its rear end from a horizontal position. A roller 8 is mounted in the upright frame 6 and this roller is held at a fixed point to be capable of rotation-on an axis extending substantially parallel with the oblique extent of the frame 6. A second roller 9 has the bearing pintles 10 thereof received through the sl' and 12 which are mounted frame 6 adjacent to the bearings in which the roller 8 is ournaled, these slide bearings 11 and 12 being arranged to be capable of movement toward and away from the bearings of the roller 8. Coiled springs 13 are secured on the frame structure, and thus these slide bearings 11 and 12 are held pressed over so that the roller 9 bears resiliently against the roller 8 under normal conditions. The frame 6 is left open as indicated at 16, at the bottom thereof in line with the line of contact of the rollers 8 and 9,- and thus as the machine may be moved across a corn field, the stalks of corn may pass through the opening 16 of the frame and through between rollers 8 and 9, due to the resilient mounting of the roller 9. It is the intention that the rollers 8 and 9 shall be constantly rotated in such directions that the stalks as gathered by the straighteners 17 and 18 which are disposed on each side of the opening 16 through the frame will be carried to these rollers and the ears of corn will be snapped or broken therefrom, and to accomplish this turning of the rollers, a driving train of mechanism is arranged from the power or bull wheel 3. This powertransmission connection embraces the frame 7 is mounted on the main frame 1 adjacent to this frame lde bearings 11 on the upright 21 carried on the power transmission shaft 1 22 which is journaled on forward part of.

with a gear-wheel 25. connected with thebearing pintle of the roller8, this latter gear-wheel25 being in turn meshed with a gear-wheel 26, of the same size and pitch, which is connected on the bearing pintle of the roller 9. A shaft 27 is connected on the main frame to extend substantially parallel with the shaft 22 and a sprocket chain 28 is passed over a sprocket 'wheel'30 on the shaft 27to impart driving movement thereto. A bevel gear 31 is mounted on the end of the shaft 23 and a bevel gear 32 carried by the shaft 27 meshes with this gear 31, the parts being thus so arranged that as the wheel 3 is turnedthrough the travel of the machine overa field, rotary motion will be transmitted to the rollers 8 and 9 to cause the same to turn in a direction that the corn stalks will bedrawn therebetween.

As the roller 9is resiliently held against the roller 8, the; corn stalks will be per.-

' mitted to pass between these rollers by spreading the same,,however, the ears of corn will offer obstructions sufliciently large that the rollers will notbe spread to permit passage of the same and consequently as the rotation of the rollers continues the stalks "will be drawn through and the ears of corn will be snapped or broken from the stalks, and to aid in the. action of taking stalks by the, rollers, it is preferable that the teeth 33 be providedthereon to work in the recesses 34jto thus grip the stalks and positively fit V V stalks are encountered which I are unusually.

the same between the rollers. It is prefer. able that the metal ribs 35 and 36' be 7 'mounted longitudinally of the rollers 8 and 9, and as these strips are here shown, they are made in the form of somewhat dull or blunt knives which workin the grooves 37 andf 38of the adjacent rollers. If for any reason'th'e rollers shouldbecome. clogged or tough and offer. greatresistance to the breaking of the ears 'ofcorn therefrom, these knives orstrips will aid in. removing the ears.

The

frame 7 has, therollers38 and 'journaled in suitable bearings carried therejoined with b' so. ei s is substantially parallel with a line taken from front to back ofzthe machine, it being preferable somewhat from'the forward ends. The shields 40 and 41 are connected with, the frame 6 and are the trough .42 whichinclines downwardly v and 9adjacent their lower ends and which that the axis of rotation ofthese roll-,

that the rear bearings be dropped from the plane of the forward bearingsso that the rear ends of these roll,- 1 ers will be ,givenagradual slope downwardly transversely ofi-the rollers 8* a bevel gear L3 is secured on the end of the shaft 22 and meshes with a gear tet carried by the roller 39, a gear-wheel 45 being provided on the shaft of this roller 39 to mesh with a gear-wheel 46 of exactly the same size which is carried by the roller 38. By this arrangement of the driving mechanism,- turning movement is transmitted to the rollers 38 and 39 so that they turn over and downwardly toward each other. The rollers 38 and 39 are spaced sufficiently'closely together that the ears of corn cannot pass downwardly there-between, although it is preferable that some slight clearance be given between these rollers to allow passage of the husks, but under all circumstances the rollers 38 and 39 will he held sufficiently It is the intention close together that the loose. ends of corn husks remaining on the ears as" discharged through the trough 42 willbe caught between therollers and carried there-through while the ears of corn will be held against passagebetween the rollers and in this way the husks will bestripped off and after pass ing through the rollers will be deposited upon the ground between the rows of stalks.

The inclination of the rollers 38 and 39 rearwardly causes the ears of corn to benot only rolled overand turned by the constant rotation of these, rollers, but also the ears will progress rearwardly over lengths of the rollers and after being thuspresentedto the stripping action of the rollers for some time will pass over the rear end of' the rollers and fall upon the ground between the rows of standing stalks.

Whileitis of courseres'sential that the rollers 8 and 9 as well as the rollers 38 'and 39, all of which receive turning movement from ,the shaft 22 shall be constantly rotated during the operation of the machine in itstravelacross. a field to takethe ears of corn from' the stalks and strip the husks, from the ears, when the machine 'is being moved to and from the field andrat other times, it may bedesirable to stop rotation of .these parts and I therefore provide the:

ing 16 of the frame 6 where they will be caught by the teeth 33 of the rollers 8 and 9 to thus be carried through between these rollers. The springs 13 will be flexed sufliciently that the roller 9 will move from the roller 8 a suflicient distance that the stalks will pass there-between and as the ears are encountered by the rollers 8 and 9, the drawing tension on the stalks will still be continued and the ears will be held against passage between the rollers which will cause the ears to be snapped or broken from the stalks and freed to fall into the shields 40 and 41 from which they pass through the trough 42 to be deposited between the side boards l9 and and upon the rollers 38 and 39. The rotation of these rollers 38 and 39 will cause the ears to be rolled and moved thereon and loose ends of the husks will be caught between the rollers and drawn and stripped from the ears while the ears will pass along throughout the lengths of the rollers 38 and 39 and will be precipitated over the rear ends thereof to be deposited on the ground The husks which are stripped from the ears by the rollers 38 and 39 will be deposited upon the ground in advance of the dropping of the ears, and thus the ears will for the most part be held out of contact with the ground and will thus be prevented from absorbing moisture which might be otherwise taken in should the corn be permitted to lie in direct contact with the ground.

From the foregoing it will be seen that I have provided a machine which may be operated either by the useof draft-animals or through the employment of mechanical power means, and which has the parts there of so arranged that the ears of corn are taken from the lower portions of the stalks and then from the upper portions and on up to the tops, thus distributing the working load upon the machine to better advantage,

1 that these ears as broken from the stalks are deposited upon the means for stripping the husks there-from and that the husked corn is then discharged from the machine in a straight and even line so that it may be readily gathered.

While in the foregoing description and illustration I have described the machine in only one adaptation thereof, it will be understood that a number of variations and modifications might be resorted to in the form and arrangement of the parts without departing from the spirit and scope of my invention, and hence I do not wish to be limited to the exact disclosure but only to such points as may be set forth in the claims.

I claim 1. In a corn husker, a snapping mecha nism comprising a pair of rollers yieldably retained in contact, each having a circumferential series of openings at one end, a circumferential series of radial teeth on one end of each roller to enter said openings of a co-acting roller during rotation of said rollers to engage the stalks therebetween, knife blades mounted in the roller between the teeth and extending radially beyond the surface of the rollers and longitudinally thereof, said rollers being provided with longitudinally extending grooves to receive said knife blades during rotation of said rollers to snap ears from said stalks.

2. The combination with a pair of snapping rollers arranged in a substantially upright position, of a pair of shields extending over said rollers and having their inner longitudinal edges spaced apart for the accommodation of stalks, and a trough arranged above and transversely of and inclined downwardly of said rollers at the lower ends of said shields for directing the ears of corn from said rollers.

In testimony whereof I aifix my signature in presence of two witnesses.
